SILO-MOLD.

Specification of Letters Patent.

Patented Mar. *7, 1916.

Application filed August 24, 1914. Serial No. 858,309.

To all whom it may concern Be it known that I, SET EDDY, a citizen ofthe United States, residing at Erie, in the county of Whiteside andState of Illinois, have invented certain new and useful Improvements inSilo-Molds, of which the following is a specification.

My invention has reference to silos, and the manner of constructing thesame, the purpose being to produce a silo of cylindrical shape whichwill be disposed in horizontal instead of the usual vertical position,and which is designed to be partially or entirely inclosed by the earth,except at one of its ends. By this means danger of the contents beinginjured or destroyed by action of the frost is precluded. The preferredform hereinafter shown and described is also provided with a centrallongitudinal partition, dividing the silo into two similar compartments,from one of which the ensilage may be removed Without disturbing thecontents of the other compartment.

In the drawings: Figure 1 is a cross-section of a silo in process ofconstruction, showing one of the temporary cross-frames used therein.Fig. 2 is an enlarged detail of the supports 1 and 2 at the point ofunion thereof. Fig. 3 is a similar View of one of the braces 9. Fig. 1shows one end of the silo and closure therefor.

The silo is preferably formed partially under ground, and for thispurpose an excavation of suitable form is made and the lower arc of thewall of the silo formed of concrete, as indicated at A. At intervalsthroughout the length of the excavation are mounted temporary framesconsisting of uprights 1, connected with which are extensions 2, securedto the parts 1 by means of bolts 3 passing through two or more of aseries of holes 4 in the plate 2, and similar openings 5 in the part 1.By this means the parts 1 and 2 are capable of vertical adjustment withreference to each other. The uprights 1 are provided with flanges 6, andthe plates 2 with flanges 7 the part 1 being further provided withperforated lugs 8, to which are pivotally connected cylindrical braces9, provided with telescopic sections 10, adapted to be held frommovement by means of set-screws 11. At their outer ends the sections 10are pivoted to shoes 12, by means of which plates or boards 13 are heldin place, such plates forming the inner wall of the form within which isconstructed that part of the silo Wall indicated at B, the side of theexcavation establishing the outer wall of the form.

The uprights 1 are arranged in pairs, spaced apart, so as to permit theconstruction of a central Wall of concrete, as shown at C, the formtherefor being provided by boards or plates 14: held in place by two ormore of the posts 1 and extensions thereof. The wall C is carriedupwardly coincidently with the construction of the outer Walls of thesilo.

The sections 2 are'providedwith series of perforated lugs 15, to whichare pivotally connected braces 16, similar to the braces 9, and providedwith extensible sections 17 pivoted at their outer ends to shoes 19,which hold in place the continuing form-plates 13, for the upper part ofthe structure. In forming that part of thesilo which is above thesurface of the ground, as indicated at D, it is necessary to use outerplates 20, connected with the plates 13 by means of bar hooks 21. 'Thecenter wall C is raised to the full height of the silo, and the sidewalls brought upwardly until the circle is completed. The braces 9 and16 are then loosened and the frames to which they are attached areremoved through the end of the silo. The plates 13 and 14: are alsoremoved, and can be used again in the building of additional silos.

After the silo is completed the upper exposed part thereof can be bankedor covered with earth, so as to make the same entirely frost-proof. Ifpossible to do so it is preferred to form the silo with one end againstor into a hill or rise in the ground, the inner end being provided witha solid wall of cement, or such material as is desired to be used.

It will be apparent that the braces 9 and 16 act in both directions whenin position, the outer ends thereof aiding in supporting the plates 13and the-inner ends preventing outward movement of the plates 14.

By having the plates 2 vertically adjustable upon the uprights 1 theframes can be used for silos of varying diameters, which would inpractice approximate 1 from ten to twenty feet. In the construction ofthe smaller sizes the inner ends of the braces 9 and 16 will pass eachother Without interference.

The outer end of the silo is inclosed by means of a barrier 22, (Fig. 4)provided on each side of the Wall C With a vertical opening havingframes 23 and removable doors 24. These doors may be provided Withsuitable fastening means and are of any desired construction, no noveltybeing claimed for this feature of the device.

Through the double construction of the silo it is possible to remove thecontents from one side thereof Without disturbing that of the otherside, which can thereby be kept for a greater length of time on accountof not having been exposed to the air. In the usual silo, upon the samebeing opened the entire contents thereof is exposed to the action of theair immediately.

What I claim as my invention, and desire to secure by Letters Patent ofthe United States, is:

In a device of the class described, a series of frames provided Withvertically adjustable sections; a similar series of frames spaced apartfrom said first named series; sectional retaining Walls held in spacedrelation With each other between said series of frames, and adapted toreceive a quantity of concrete to form a central Wall for said silo; aplurality of braces externally and pivotally connected With each of saidframes, and provided With extensible sections; shoes pivotally attachedto the outer ends of said braces; and form-plates adapted to be held inplace by said shoes, and proviue a form for a silo Wall.

In testimony whereof I aliiX my signature in presence of two Witnesses.

SETH EDDY.
